IMPROVEMENT IN THRASHlNG-MACHINES.

Specification formingpart of Letters Patent No. [95,5 856, dated September 25, 1877; application filed January 10, 1876.

It turns but one way, and has a pulley on it for carrying the elevator-cups. It receives the tailings caught by tail-board u, conveys them to the side of the machine, where an elevator returns them to the cylinder. 2 2 are the sills of the machine. They are spliced in the middle for the purpose of allowing the front wheels of trucks on which the machine is carried to turn under them.

For convenience in making or repairing the machine the outer shell or case may be made in several pieces and bolted to the upright posts 4 and 6 of the thrasher-frame, as shown in dotted lines in Fig. 1.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, substantially as specified, of the concave and the eccentrically-journaled cross-girt a.

2. In combination, the winnowing-shoe L, having the tail-board u and the tailings-shoe 12, substantially as set forth.

3. In combination with the winnowing-shoe L, the tailings-shoe '1), provided with the movable shelf a: and movable finger-strips 3 substantially as set forth.
